Active guitar controls

[obblitt]

Does anyone play around with active in-guitar EQing or tone controls? I didn't really know what to search for, and not much came up.

This is what gave me the idea (the last two on the page): http://www.muzique.com/lab/tstone.htm - I hope it's not a problem posting that link? How am I supposed to know that stuff anyway?

My idea was (if you'll look at the very last example) to get that kind of response but with the treble peak reversed, so as you turn the "tone" pot, the mids come way up and the treble goes down. I could really use a super responsive control like that in my guitar, as I do a lot of experimental playing with my band, and do a lot of ambient, textural stuff.

Is there some kind of page similar to the one I've linked to that explains active guitar controls?

  Joe Gagan had a passive wah wah in his Tele.
  He'd sanded the potwafer [fancy pot too IIRC] and used a kirkpacitor of some specially chosen [small cap] to produce a wah tone using the re-wired tone control on the guitar.
  Alternative:
  Volume pot [a largeish value], with a bypass capacitor across it's signal lugs.
  As it is I diddled with values and use those bypass caps on guitars, they all work, the one guitar has pretty aggressive frequency shift toward treble with volume control adjust between 10 and 8.
  Sometimes [certain PU's or Pots I guess] they're easier to get going to a profound degree of 'treble boost' sound [even though it's technically a passive circuit].
